US Energy Mix

Electricity Generation (~40% of total):

50% Coal, 20% Nuclear, 18% Natural gas, 3% Petroleum

Transportation Fuels (~30 % of total):

96% Petroleum Very little overlap between energy sources for these two dominant sectors!

Next Energy Plan

  • Reducing Delaware’s Energy Usage
  • Reducing Environmental Footprint of the

Energy Delawareans Use

  • Having Effective and Efficient Energy

Transmission and Distribution Systems (for any type of energy or fuel)

  • Reducing the Energy Impact of Transportation

in Delaware

  • Maximizing Delaware’s Clean Energy

Economic Development Opportunities

Per capita energy use was ~357 million BTUs in 1999, and 372 million BTUs in 2005, a growth of 4.2% over the 6 year period. US average 2005 per capita energy use was 339 million BTUs; Delaware ranked as the 19th largest per capita user of energy. States with the lowest and highest 2005 per capita energy use were: Rhode Island 213 million BTU New York 217 million BTU California 232 million BTU Wyoming 912 million BTU Alaska 1,192 million BTU 2005 per capita use was lower than Delaware in all neighboring states: Delaware 372 million BTU Maryland 279 million BTU New Jersey 315 million BTU Pennsylvania 327 million BTU A note that should be made, Delaware’s per capita figures are affected by refineries and power plants vs. the relatively small population.

SLIDE 30

Key Questions to be Addressed by the Work Group:

  • 1. What policies and programs can be put into place that will reduce the

environmental footprint of Delaware’s energy use?

  • 2. How should Delaware meet its current and future electricity

requirements?

  • 3. What will the impact be on Delaware’s electricity generation system

as the price of coal rises? The price of natural gas? The price of carbon?

  • 4. What can be done to moderate price shocks or create price stability
  • ver time? What is the likelihood of price stability or instability?
  • 5. What is the likelihood of future regulations impacting the energy type

used to generate electricity in Delaware?

  • 6. What should be the appropriate balance between regionally

generated electricity and transmission from distant generation facilities?
